<hr/>
<p><b>This example will display a basic progress bar while retrieving a large file.</b></p>

<p>We have created a Request/Listener class HTTP_Request_DownloadListener on lines 18 to 104.
In this Listener, a progress bar was integrated on lines 78 to 84. It's a basic progress bar
with only one render option changed (animation speed).</p>

<p>On lines 90 and 92 the progress bar is updated depending of the data size already received.</p>

<p>Media file is identify by URL defined at line 106.</p>

<p>When the shockwave flash object is fully loaded, page sw4p.html is shown on lines 115 to 117.</p>
